Abstract

Griscelli syndrome (GS) is a rare autosomal recessive disorder resulting in pigmentary dilution of the skin and hair with variable phenotypes depending upon subtypes. Mutations in 3 distinct genes MYO5A, RAB27A, MLPH are responsible for 3 subtypes (GS1, GS2, and GS3) of GS respectively. GS subtype 2 commonly develops hemophagocytic lymphohistiocytosis (HLH) and recurrent infections due to immunodeficiency. We hereby report a 20 month old male child presenting with silvery gray hair, hypomelanosis and features of hemophagocytosis. The diagnosis of a type 2 GS was made in response to a set of clinical features: hypopigmentation of skin and the silvered reflection of the hair, absence of psychomotor retardation, the occurrence of an accelerated phase (hemophagocytosis) and, above all, a pathognomonic appearance by microscopic examination of a hair. The absence of giant granules in the nucleated cells made it possible to eliminate Chediak-Higashi syndrome, which shares a close clinical spectrum with GS. This case promotes awareness about this rare case of GS as a high indicator of suspicion about this potentially fatal condition and aids in prompt diagnosis and foresees complications. Early bone marrow transplant is the only curative treatment for GS-2.
